Hi me and my boyfriend has been always sexually active. We dont use any protection at all. My period has always been irregular but either way I always get it each month. I have gotten pregnant before but I got a miscarriage and that was like 5 yrs ago. My last period was around july 14 2012. And now its october 9 2012. So ive missed my period for about 2 to 3 months. Ive taken a pregnancy test about 2 weeks ago but it came out negative. On saturday I spotted very light it was light brownish/pinkish when I went to the bathroom and I wiped. I thought it was my period but in the same day it was gone. It didnt even last long at all. After that I never bleeeded again. Is this implantation bleeding ? Its obviously not my period and I always feel as if theres something in my stomach. And around my abdominal area. What are my chances of being pregnant? What should i do ? Please help me !
